Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the sensor module is attached to the body using a separate applicator, then the sensor module can be attached to the skin, but the user must perform multiple complex operations including inserting the sensor module into the applicator and additional follow-up procedures
Solution Approach 1:
The sensor module is pre-installed in the applicator during fabrication, merging two separate components (sensor module and applicator) into a single integrated assembly. This eliminates the need for users to manually insert the sensor module into the applicator and perform multiple follow-up procedures, reducing operational complexity while maintaining the ability to attach the sensor to the skin
Solution Approach 2:
The sensor module is pre-installed in the applicator before use, performing the assembly action in advance during fabrication. This preliminary action eliminates the need for users to perform complex assembly operations at the time of use, simplifying the user interface while preserving the functional capability of attaching the sensor to the body
2Reliability
If a separate transmitter is used with the sensor module, then the transmitter can transmit glucose data, but the transmitter must be disposed of along with the sensor module despite being reusable
Solution Approach 1:
The transmitter is separated from the disposable sensor module and applicator assembly. The transmitter can be reused while the sensor module and applicator are disposed of after a single use. This recovers the valuable transmitter component from the single-use pathway, reducing waste while maintaining reliable data transmission functionality
Solution Approach 2:
The system is divided into disposable components (sensor module and applicator) and a reusable component (transmitter). This segmentation allows the transmitter to be separated from the single-use assembly, enabling its recovery and reuse while the sensor module and applicator are discarded, thus reducing material waste while preserving data transmission reliability
3Loss of substance
If the sensor module and applicator are made reusable, then economic costs are reduced, but measurement accuracy and safety are compromised
Solution Approach 1:
The sensor module and applicator are designed as disposable, single-use components that are discarded after one use. This ensures measurement accuracy and safety by preventing contamination or degradation from reuse, while the transmitter is reused to minimize overall waste. The disposable nature of the sensor module and applicator maintains precision while the reusable transmitter reduces material loss

AI summary
The present invention relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.
